Wednesday's lander work focused primarily on measuring, designing, and fabricating custom shims for installation of the last two bulkheads. Deformation from the weld leaves an irregular contour on the frustrum, creating an irregular gap where the final bulkheads are to be installed.
The shims will conform to the contour and enable the bulkheads and angled brackets to fit securely to the frustrum.
